Evaluate 5x-2y-+4z when x=3,y=2and z=4
To evaluate 5x - 2y + 4z when x = 3, y = 2, and z = 4, substitute the given values into the expression:
5(3) - 2(2) + 4(4)
= 15 - 4 + 16
= 27
Therefore, when x = 3, y = 2, and z = 4, the value of 5x - 2y + 4z is 27.
To evaluate the expression 5x-2y+4z when x=3, y=2, and z=4, we substitute the given values into the expression.
So, we have:
5(3) - 2(2) + 4(4)
First, let's solve the multiplication:
15 - 4 + 16
Next, let's perform the addition and subtraction:
15 - 4 + 16 = 27
Therefore, when x=3, y=2, and z=4, the value of 5x-2y+4z is 27.
To evaluate the expression 5x - 2y + 4z when x = 3, y = 2, and z = 4, you simply substitute those values into the expression and perform the necessary calculations.
First, substitute the values of x, y, and z into the expression:
5(3) - 2(2) + 4(4)
Next, perform the operations following the order of operations (PEMDAS/BODMAS):
5 * 3 = 15
2 * 2 = 4
4 * 4 = 16
Then, substitute the calculated values back into the expression:
15 - 4 + 16
Finally, carry out the remaining addition and subtraction:
15 - 4 = 11
11 + 16 = 27
Therefore, when x = 3, y = 2, and z = 4, the expression 5x - 2y + 4z evaluates to 27.
